Abstract: A cooling system for a fuel cell vehicle is provided to integrate a condensed water circulating line with a coolant circulating line, so that thermal exchanges of a radiator of the deleted condensed circulating line can be compensated by a cooling pipe, thereby configuring the cooling system in compact size. A hydrogen supply line is configured to pass through a humidifier(11), a fuel cell stack(13), and a hydrogen condenser(15). The humidifier(11) humidifies supplied hydrogen to supply the humidified hydrogen to the stack(13), and condenses non-reactive hydrogen discharged from the stack(13) in the hydrogen condenser(15). An air supply line is configured to pass through the humidifier(11), the fuel cell stack(13), and an air condenser(17). The humidifier(11) humidifies a supplied air to provide the air to the stack(13), condenses a non-reactive air discharged from the stack(13) in the air condenser(17), and discharges the condensed air. A pump(19) transfers a coolant provided from a radiator(23) to the stack(13) and the air condenser(17).
